ATTACHMENT FOR DISK HARROWS.

To all 'whom t may concern:

Be it known ,that I, FERD Nonoxnn, a citizen of the United States, residing at Sanborn, in the county'of Barnes, State of North Dakota, have invented certain new and useful Improvements in Attachments for Disk I-Iarrows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an for disk harrows. f y

An object of the invention resides in the provision of a device which may be secured between the two inner disks on a disk harrow to relieve the strain which tends to force the said disks apart.

A further object of the invention resides in so constructing the' devicel that yit will permit the adjustment of the disks.

With these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as set-forth in and falling within the scope of the appended claims.

Referring to the drawing: Figure l is an elevational view showing my device in place on a disk barrow, only a portion of the harrow being shown, however. Fig. Qis a. longitudinal sectional view of my device. Fig. 3 is a section on line 3-3 of Fig. 2. Fig. 4 is a fragmental detail of the means for securing the device tothe harrow disks.

Referring to` the drawing wherein like parts are indicated by like characters throughout'the several views: In the drawing, I have illustrated a portion of a harrow which includes a pair of beamsl which are attachment pivotally mounted atv l upon a frame 2.

The angular relation kof these beams 1 may be varied by the operator by means of a pair of levers 3 which are connected to the beams by links 4 and are held in their adjusted positions by the coperation of, pawls thereon with a quadrant rack 5. Depending from beams l are arms 6 on the lower ends of which bearings 7 are mounted. Spaced disk shafts 2 are mounted in these bearings rand support disks 3, the innermost disks being spaced from each other. In order that these shafts may be strengthened and the end Specification of Letters Patent.

thrust taken oft of the shaft bearings I have provided a pair of socket members 4L which of which plates bears against one side of the` adjacent flange 6. Detachably secured to these plates 8 are additional plates 9 which coperate with the plates 8 to form channels on the caps 7 in which the flanges 6 are located. Extending outwardly from the caps 7 and slidably mounted therein are rods IO, the outward movements of which are limited by the heads 11 thereon. The ends of these rodsk are joined together by a ball andy socket connection midway between the said disks. In using the device the rods 10 will brace the disk shafts so that the end thrust will be taken off of the bearings and when the shafts are adjusted the heads 11 on the shafts l0 will ride in the caps 7 so as to allow such adjustment. It will thus be seen that I have provided an attachment for disk harrows which consists, essentially, of a pair of rods swiveled together which extend between the innermost disks and are secured to the inner ends of the disk shafts so that the force tending to separate the sets of disks will be taken up by the said rods and thus the end thrust on the bearings for the shafts will be overcome.

lVhile I have illustrated and described a particular embodiment of my invention, I have merely done so for the sake of convenience and I do not wish to be limited to the particular embodiment as it is obvious that numerous changes may be made' within the details of construction thereof without in anyway departing from the spirit of the invention or exceeding the scope of the appended claims.
